Thomas Kurz: “Greenhouse Gases and Climate Feedbacks” | Tom Nelson Pod #419

<p>Thomas Kurz discusses chapters from his book Why There Is No Climate Crisis, citing positive reviews, then explains the greenhouse effect and argues CO2’s warming is limited and logarithmic. He claims doubling CO2 yields about 3 W/m² effective forcing, or ~0.9°C via Stefan–Boltzmann calculations, and says even burning all known fossil fuel reserves would add under ~1°C. He argues “climate crisis” claims rely on compounded positive feedbacks in IPCC models, but says observations show models overpredict warming, relative humidity aloft is declining, and a predicted tropical hotspot is missing. He attributes discrepancies to cloud/aerosol cooling, proposing an Earth “thermostat” and net slightly negative feedback.</p><p><br></p><p>00:00 Guest and Book Update</p><p>02:31 Greenhouse Effect Basics</p><p>04:53 CO2 Absorption and Saturation</p><p>07:38 Four Ways to Calculate Forcing</p><p>17:11 Convert Forcing to Temperature</p><p>21:19 Logarithmic Warming Limits</p><p>24:20 Fossil Fuels and Max Warming</p><p>28:13 Feedbacks Behind the Crisis</p><p>32:55 Models vs Observations</p><p>41:30 Clouds and Cooling Evidence</p><p>55:51 Earth Thermostat Conclusion</p><p>57:52 Q&amp;A and Scientific Method</p><p>01:01:33 Wrap Up and Farewell</p><p><br></p><p>“Why There is No Climate Crisis: The Surprising Evidence You Should Know”: <a href="https://a.co/d/05rKxsYU">https://a.co/d/05rKxsYU</a></p><p><a href="https://www.whynoclimatecrisis.com/">https://www.whynoclimatecrisis.com/</a></p><p>Email: info@WhyNoClimateCrisis.com</p><p>=========</p><p>Slides, summaries, references, and transcripts of my podcasts: <a href="https://tomn.substack.com/p/podcast-summaries">https://tomn.substack.com/p/podcast-summaries</a></p><p>My Linktree: <a href="https://linktr.ee/tomanelson1">https://linktr.ee/tomanelson1</a></p>
